My choice of tags takes into account this site’s full-text search. If a visitor wants to read about a particular species — say white-tailed deer or lupine — the search results will create a list of observations. I considered offering tags by “Taxa” (species, genus, family, etc.), but that would be far too granular for most visitors — and given my lack of formal training, create opportunities to introduce errors. I settled on the general, single-level tags below as a “Goldilocks” solution (not too big, not too small).
